RESISTAL: Evaluation of the Efficacy of Somatosensory Rehabilitation of Pain by Vibrotactile Stimulation on Static Mechanical Allodynia
Study Details
Study Description
Brief Summary
This study aims to demonstrate that somatosensory rehabilitation of pain associated with static mechanical allodynia has superior efficacy over placebo treatment as well as over spontaneous changes.

Detailed Description
This is a monocenter study. 45 patients will be enrolled in the study, allocated by randomization in 3 arms of 15 patients each.
During the 38 week duration of the study, enrolled patients will be assessed at:
-
initial evaluation (first week of the study),
-
intermediary evaluation for every week and every modification of intensity of pain,
-
final evaluation at 10 weeks,
-
follow-up evaluation at 6 months.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Vibrotactile stimulation Patients in this arm will have treatment by medications and rehabilitation treatment by vibrotactile at medical center stimulation at home by soft tissue non stimulation on allodynia area |
Other: Standard Medical treatment
Standard treatment with drugs and usual rehabilitation
Device: Vibrotactile stimulation
Rehabilitation by vibrotactile stimulation at medical center
|
| Sham Comparator: Sham Stimulation with Vibradol device switched off Patients in this arm will have treatment by medications and rehabilitation Sham vibrotactile treatment at medical center but with Vibradol device switched off abdominal breath exercises at home non stimulation on allodynia area |
Other: Standard Medical treatment
Standard treatment with drugs and usual rehabilitation
Device: Sham Stimulation with Vibradol device switched off
Sham Rehabilitation at medical center but with Vibradol device switched off
|
| Other: Standard Medical treatment Observational group, treated as usually by medications and rehabilitation. |
Other: Standard Medical treatment
Standard treatment with drugs and usual rehabilitation

Outcome Measures
Primary Outcome Measures
- Change of baseline in reduction of surface of allodynia area [At baseline, each week during the 10 week treatment period and at 6 months]
Evaluate by the 15 g mono filament (Allodynographie) the reduction of surface of allodynia area
Secondary Outcome Measures
- Change of baseline in reduction of pain [At baseline, at each week, at 10 weeks and at 6 months]
Reduction of pain will be evaluated by QDSA questionnaire.
- Change of baseline in reduction of allodynia intensity [At baseline, at each week, at 10 weeks and at 6 months]
Reduction of allodynia intensity will be measured with the method with the colors
- Change of baseline of patient's satisfaction with regard to received care [At baseline, at each week, at 10 weeks and at 6 months]
Patient's satisfaction with regard to pain relief will be evaluated by VAS
- Analgesics consumption [At 6 months]
Amount of analgesic drugs
- Afterglow effect [At 6 months]
An evaluation of static mechanical allodynia in surface and intensity at 6 months
